Referring now more particularly to Figures 1 and 2, there is shown a tractor l0 having alongitudinally extending body portion I i and a transversely extending rear axle structure l2 disposed atright angles with respect to the body portion. Through this axle structure i2 extends a rear drive axle I3 for connection with traction drive. wheels. I4 joumaled .on the stub axle housings l5 and l6 depending from the are removed iromthe centrally disposed bracket structure and are moved to one side where one portion l1 having on its bottom face attaching of the leg portions. or each bail'is connected to but one of the vertically extending portions of the central bracket, while the other .leg portion I is connected to another bracket structure laterally disposed and transversely alined with the centrally disposed bracket structure. 0n. the

opposite side of the tractor a similar-"auxiliary outer ,ends of the transverse rear axle structure intermediate the ends otlthe transverse axle structure l2, and at" the connection of the body portion -ll therewith is provided an expanded portions l8; 'anda flattened top surface i9. Connec'ted' to this expanded or enlarged-portion 1|! is a bracket, structure 20 having laterally spaced, verticallyextending portions 2i and 22. These portions are-connected to; the attaching portions bracket structure is disposed in'transverse ahnement with the central bracket structure-and a new set of vertically spaced balls is connected therebetween in a similar manner. The lifting bail iscarried on the centrally disposed bracket structure and extends sumciently so that it will contact with the bail membersof the respective working tools and through which lifting is efiected; The single tool is gauged from the tracexpanded [8 of the expanded structure I! by-attaching pieces 23 and '24 made fast with the. tractor by .mea-ns' of bolts 25.

The upper ends of the vertically extending portions 2| and 22 are retained in spaced relation and connected to the expanded portion. ll by means of a bracing means 26 adaptedto be secured to the top face is of the portion H by means of .fastening bolts fO n the vertically extending portion 2| of the spaced openings 28 and 29 adapted to receive, respectively, the leg portions of a pair of spaced bail members 30 and 3|. The opposite leg portions of the bail members 30 and 3| are adapted to be retained by openings 32 and 33 within the 4 bracket structure by means of vertically spaced bracket structure is provided a pair of vertically laterally extending portion 22 at the right side of the tractor. The transversely extending closing portions 34 and 35 of the respective bail members 30 and 3| are free for vertical movement and are adapted for the attachment thereto of a vertically extending stub beam 36 which has a working tool or plow bottom 31 on its lower end. It should now be apparent that therehas been provided by the bail members means for connecting a working tool 31 to the bracket structure, and such means is of the type to give substantially the usual effect of parallel links to the working tool while in operation, To each of the laterally disposed, vertically extending portions 2| and 22 of the bracket structure there are connected power lifting bail-attaching plates 38 and 39 adapted to be respectively secured thereto by clamping means 40 and 4|. Extending transversely of the bracket structure and adapted for connection to these' attaching pieces 38 and 39 is a lifting bail 42 having a transversely extending portion 43 of suflicient width and adapted to contact with both legs of the connecting bail 30. The lifting ball has its leg portions pivoted to the attaching pieces and can be rotatballs and adapted to be operated by a fluid-operated device to lift the same to a transport position.

Description will now be made of the means for converting this single tool attachment into an attachment of the type having two tools, wherein use may be made of the parts already used for the single tool type attachment. When it is desired to make a tool attachment having two tools, the tool 31 and the balls and 3| are detached from thebracket structure '20 at their points of connection with the respective vertically extending portions 2| and 22. On the stub axle housings l5 and |6,-laterally spaced from the bracket structure 29, there isrespectively disposed brackets 62 and 63 having respectively ex-. tending portions 64 and 65. The attachment ofthese brackets 62 and 63 is respectively made by clamping bolts 66 and 61. Thespacing of these bracket structures 62 and 63 is of suflicient distance to permit the connection of the bail members 30 and 3|. The bail member 30 may be removed from the bracket structure 20 and one of its leg portions seated in an opening 64' in the bracket structure 64. The other leg portion may be connected to the opening 28 in the vertically ed with respect thereto and in a vertical direcsource may be that of the exhaust gases takenv from the engine of the tractor, as indicated at 50, in a manner shown and described in the patent application to Carl W. Mott, Serial No. 353,099, filed August 17, 1940. The fluid device 46 includes a piston rod 5| connected to the arm 45, as indicated at 52. As the rod is extended rearwardly, the lifting bail 42 is rotated upwardly in a clockwise direction for contact with the bail member 30, the same contacting with the leg portions of the lifting bail 36, as indicated at 53 and 54. As themovement is continued. the

:working tool 31 will be lifted to a transport position.

extending portion 2| of the bracket structure. The lower bail member 3| is removed and one of the leg portions thereof is connected to an opening 64", while the other leg portion thereof will be seated in the opening 29 of 'the vertically extending portion 2| of the bracket structure 29. It should thus now be apparent that with the bracket structure 64, the working tool 31 and its connecting bail members 30 and 3| may be moved to the left and there connected for movement with respect to the tractor. Use is there-, by made of the central bracket structure 20 to aid in supporting the working tool in its laterally removed position. The bail members 3|) and 3| are thus the same bail members such as used on the attachment of the single tool type.

At the right of the tractor, as shown in Figures 3 and 4, a new set of upper and lower bail members 16 and 1| are provided. These bail members are of the same shape and size as the bail members 39 and 3|, respectively, and have the same leg portions thereon. The outer ends of the bail members at their transverse portions serve to support a working tool 12, which is connected to the bail members by means of a stub beam 13, all of which is similar to the stub beam 36 and working tool 31. Use is made of the fvertically extending portion 22 of the bracket structure 26 for the connection of the leg portion at the left of the bail members, while the bracket structure when the working] tool is in its working position, it will be retained in that position by a depth-adjusting means 55 having a lever 56 accessible'to the operators station 49 and adapted as indicated at 66. As the tool is lowered, the

slack in the chain 59 is taken up to its extended limit, the tool there to be retained in its working position, There hasnow been described an attachment of the type having a single working 63 serves for the connection of the leg portions at the right of the bail members. The right leg portion of the upper bail member 16 connects in an opening 65' in the bracket member 63, while the right leg portion of the lower bail member 1| connects in an opening 65" thereof. Itshould thus. now be apparent that, in the converting of the single tool attachment into an attachment having two tools, use is made of the central bracket structure, 20 for the connection of the tools and that it ,is only necessary for the contool which is connected toa centrally disposed side of the tractor is provided a manual adjusting'means 14 having the same parts as the manual adjusting means 55, and it is connected by means of a chain to the lower link] I, as indicated at 16. This manual adjusting'means will thus serve to regulate the working depth of the 4 'second tool 12. The manual adjusting means 55 serves to regulate the working depth of the original tool 31, the connection of the manual adjusting' means being made with the lower bail member 3| on its right leg portion instead of its leftleg portion and as indicated at H.

On referring to Figure 3, it will be noted that the lifting bail 42 is of sufficient width to extend considerably beyond the sides of the bracket structure 20. This'width is sufficient so as to engage with the right-hand and left-hand leg portions, respectively, of the upper bail members 30 and I0. It is thus apparent that it is not necessary to change the lifting mechanism in any way to make the same adaptable for use when the attachment is converted into one having two working tools. The lifting ball 42 thus remains in the same position and is of the same shape as the bail used in the lifting of the single tool attachment, as shown inFigure 1.
